Subject: [PATCH 2/2] Revert "m68k: set dma and coherent masks for platform FEC
 ethernets"

This reverts commit f61e64310b75733d782e930d1fb404b84699eed6.

Initializing the coherent dma mask for a m68k platform device
with DMA_BIT_MASK(32) is no longer necessary because
arch_setup_pdev_archdata() now does so by default.
